Massive Cranking Performance: 500 CCA

Standard batteries often struggle with the resistance of a large V-Twin engine, especially in cold weather. The Twin Power Shocker solves this with an industry-leading 500 Cold Cranking Amps (CCA). Combined with a 32Ah capacity, it offers unmatched reserve power. This makes it the ideal choice for “baggers” equipped with high-wattage amplifiers, heated seats, navigation systems, and extensive LED lighting kits that put a heavy strain on the charging system.

Advanced AGM Construction for Extreme Durability

Touring motorcycles subject batteries to prolonged heat and constant road vibration. The TPZ32HL-BS utilizes Absorbed Glass Mat (AGM) technology, where the acid is absorbed into fine fiberglass mats. This creates a highly stable internal structure that is 100% leak-proof and spill-proof. The internal plates are reinforced with a full-frame grid design to prevent shedding and internal shorts, ensuring the battery survives thousands of miles of highway travel.

Patented Conductivity & Superior Terminals

Poor connections are a leading cause of electrical failure. Twin Power features patented flush-mount terminals with a brass-embedded nut. This design provides a significantly larger contact area compared to standard lead posts, offering up to 50% better conductivity. These heavy-duty terminals minimize voltage drop and heat buildup, ensuring that maximum power reaches your starter and accessories without the need for frustrating spacers or shims.

Factory Activated: Plug and Play Convenience

Riders value their time on the road, not in the garage. This battery is Factory Activated, meaning it arrives fully charged, sealed, and ready for immediate installation. There is no hazardous acid to pour and no initial slow-charge required. Its maintenance-free, Valve Regulated Lead Acid (VRLA) design means you never have to check fluid levels, providing a “set it and forget it” experience for the life of the battery.
